Patented April 27, 1909.

Application led March 30, 1908. Serial No. 424,247.

T o all whom 'it may concern.'

Be it known that l, Isaac FRANCIS TAY- LOR, of 5 Upland road, EastDulwich, in the county oi' London, England, van builder, have inventedcertain new and useful lmprovements in Cranes, Fire-Escapes, and SimilarApparatus, of which the following is a full, clear, and exactdescription, and lor which application for patent has been made,No.20,664 of 1907, dated September' 17, i907.

This invention has reference to improvements in cranes, lire-escapes andsimilarl apparatus, and has for object to provide an apparatus which isreadily adaptable to any window or opening and when litted but out ofuse not obstructive yet ready Al'or immediate use. A small winch ispivoted to a 'fixed stanchion inside lthe window or opening so that thewinch can be revolved around say, behind shutters or curtains, or can berevolved so that the j ib is outside and clear el' the wall. Thestanchion is iitted with adjustable brackets or other means so that itcan readily be attached to any window or opening, or be inclined in caseof a dormer window. The winch rope is automatically varying according tothe weight of the load.

Upon the accompanying drawings, l have shown two forms of carrying outthe in vention.

Figures l and 2 are respectively a 'front and a side elevation ol' thedevice fitted with a single ro e. Figs. 3 and 4 are similar views of adoubie rope device. Fig. 5 is an enlarged view in side elevation of thebrake support and operating mechanism. Fig. 6 is an elevation oll ageared spindle sometimes employed.

The stanchion a in Figs. l and 2 is shown suited for atliXing to theinside of a window frame and provided with sockets b b. Into thesesockets lit pivots c secured to or formed on a post c which isduplicated at d, these members c d being riveted together at top andconnected at bottom by a cross bar d to form a frame. This frame formedoll the members c d can thus swing around the pivots c and it carriesintermediate of its height a transverse spindle e suitably journaled inposition and having a squared end projecting beyond the member d asshown at e so that this spindle may be rotated by means of any suitablecrank handle. The jib f which is also a double member is pivoted at j"to the lower part of this 'frame c d and carries at its outer end apulley g revoluble on a cross pin )'i.. This pin /t also secures ashackle i in place, the other end of the shackle being connected by al'lexible connection such as a chain Z to one end ol a lever arm m theother end ol' which is pivoted in the lramc c d. intermediate ol itslength this lover 'm is pivoted to a 'forked link n which carries a loopoll stripv metal `forming a band brake o. This loop may be lined withwearing material il` desired, in the ordinary manner ol' band brakes.

Upon the spindle e is keyed or otherwise mounted a drum or pulley p onwhich may be.

wound a wire rope p and by the side ol the pulley p is a drum g aroundwhich is passed the band brake 0. The arrangement is such that when theweight of the load represented at af, see Fig. 2, tensions theconnection or chain Z the lever m is raised thereby lifting the lever nand the band brake is consequently applied to and tightened about thedrum; the braking action imparted to the drum g spindle c andrope-pulley p is directly proportionate to the load. In Figs. 3 and 4, asecond rope-pulley r is illustrated which is mounted on the spindle cand the brake drum q is shown arranged between the two pulleys. A ropeis provided on each pulley and these ropes are wound in oppositedirections so that, the spindle e being revolved in the same direction,as one rope is wound up the other is unwound. ln this ease a secondpulley g is provided at the end of the jib. More than two pulleys orWinches p r may be used if desired, a corresponding guide pulley at theend of the jib being provided for each. A third )ulley s is shownpivoted upon the undersi( e of the jib; this pulley serves to store oneof the ropes when the apparatus is closed up and out of use and the ropefrom this pulley s is not connected to the pulley r until the rope p hasbeen fully wound on its pulley p. Then the rear end of the second ropeis secured to its pulley r and that rope is wound on pulley r as therope p on pulley p is unwound. Thus whilo the apparatus remains in useone rope may always be wound up as the other is unwound.

lf desired, l may of course gear the spindle e to the pulleys p 1 anddrum q so that one revolution of these pulleys will occur to more thanone revolution of the spindle e; such arrangements in cranes andhoisting tackle are Well known and a suitable form is shown in Fig. 6,the pinion t mounted on the spindle i e meshing with a larger pinion uformed with or secured to ene of the pulleys p r.

I also provide means whereby when desired, as for instance in using asingle rope to raise goods, the automatic braking action of the bandYbrake may be avoided. Thus I have shown in Fig. 5 a lever v which whenoperated in the manner indicated will remove the tension from the link aand cause the brake drum to be freed from the brake. Other equivalentdevices might be employed for releasing the brake, as for instance byremoving the tension from the connection l.

The ends of the ropes are provided with hooks, slings or other suitabledevices dependent upon the particular purpose or purposes for which theapparatus is designed or used. Thus the improved crane can be used forraising and lowering goods from windows, for use with brewers drays,launching lifeboats and similar urposes. rhe device may also be used asa 're-escape in which case the sling or a basket, carriage or the likeis utilized. I have shown a suitable form of sling w in Fig. 4 of thedrawings. T he eye of the sling may be provided with a guide line sothat instead of falling vertically the rope may be drawn out away fromthe vertical, and this line may be passed around a pulley xed to theground or other similar support,

The support shown in Figs. 3 and 4 is more particularly suited for usewhere no uprights are available for the socket frame, or for use where abalcony intervenes between the window' and the ground.

When not in use the jib may be folded up against the frame, this beingpossible by reason of the operative connection between the jib end andthe pivoted lever m being made iexible.

Having thus described my invention what I claim as such and desire tosecure by Letters Patent is l.
